Abstract

In this work infrared thermography was used as a diagnostic tool for the performance assessment of a photovoltaic array integrated on the southern façade of NTUA's Chemical Engineering Building. This grid-connected 50 kWp solar photovoltaic array, installed under an EC Thermie Project (SE-142-97-GR-ES), operates in a standard and hybrid PV-Thermal configuration, meant to save conventional energy. The thermographic system used for the analysis covers the 8-12 ìm of wavelength region. The thermal images obtained showed that there are temperature differences on the PV panels, which may be attributed to PV material defects, manufacturing faults, external abuse, or PV malfunction.
